Snellville will run a test of a new emergency communications system Thursday.

The system, CodeRED Emergency, will begin making calls around 3 p.m. and continue until everyone in the database has been contacted. A message will be left directing recipients to the city’s website to add additional contact numbers and to spread word by mentioning the system to family, friends and neighbors.

Information: 770-985-3500 or www.snellville.org.
